Sender Comm channel issue

Hi to All.
I am facing a issue sender comm channel?

Could you please help me on this?
Thanks in advance.

3. File Locking / Incomplete Processing
Q: I sometimes observe that files are processed only partially, i.e., only a fragment from the file's start is converted into an XI message. Nevertheless, the file is usually archived completely. Does the File Sender Adapter honor if another process has locked a file for exclusive use?
A: Unfortunately, the J2EE 1.3 technology the File Adapter is built upon does not support file locking. This limitation affects the File Adapter's operation. Depending on whether the JRE implementation for the operating system under which the adapter runs uses mandatory file locking or advisory file locking, opening a file that is currently being written to by another process will fail or not.
If opening the file fails, no problem exists and the adapter will try to open the file each poll interval until it succeeds.
However, if opening the file is not prevented by the operating system, the adapter starts to process the file although it is still being modified. Since XI 3.0 SP11 / PI 7.0 there is a parameter named "Msecs to Wait Before Modification Check" in the advanced settings of the File Sender channel configuration to work around this issue. This setting causes the File Adapter to wait a certain time after reading, but before sending a file to the Adapter Engine. If the file has been modified (which is basically determined by comparing the size of the read data with the currentfile size of the input file) after the configured interval has elapsed, the adapter aborts the processing of the file and tries to process the file again after the retry interval has elapsed.
If this option is not available for the settings you would like to use, the following algorithm (to be implemented in your application) may be used to ensure that the File Adapter only processes completely written files:
- Create the file using an extension, which does not get processed by the File Adapter, e.g., ".tmp"
- Write the file content
- Rename the file to its final name, so the File Adapter will notice its existence and pick it up

JDBC comm.channel issue with MS SQL select statement

Hello,
We are using JDBC adapter to connect to an MS SQL database.
This is the comm.channel config.
com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc:sqlserver://<DNSname>:1433;databaseName=PSMI
Activation of channel is successful.
But when starting a select on a table of the database we will get this error for any table there in comm.channel monitoring.
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'TABLENAME' (structure 'STATEMENT'): com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'SAP_Header'.
Error processing request in sax parser: Error when executing statement for table/stored proc. 'TABLENAME' (structure 'STATEMENT'): com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'SAP_Header'.
Error while parsing or executing XML-SQL document: Error processing request in sax parser: Error when executing statement for table/stored proc. 'TABLENAME' (structure 'STATEMENT'): com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'SAP_Header'.
The table is existing because we can access it from excel database connect.
The connect address is the same in Excel as in comm.channel.
Installed driver is for JDBC for 2000/2005 (1.2/4). for JDK 1.4
Your help is really appreciated!
Best regards
Dirk

Hi Dirk,
This is the comm.channel config.
com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc:sqlserver://<DNSname>:1433;databaseName=PSMI
I hope the DNSname you using is your Server name of the SQL Server (IP/ServerName) you trying to connect to.
Please ensure that if you are using Hostname the entry is made in the host file at server level against the IP.
Try using the Connection string as :
jdbc:microsoft:sqlserver://IP(hostname)\ServerName;DatabaseName

Polling/Sender comm channel in clustered environment

Hi Experts,
Our PI7.1 system is currently setup on two java clusters.
I was searching for a guide on how to handle polling using these two clusters, but it seems I can't find one yet.
Do you know where I can find these?
What we were trying to do is disable a comm channel in one node but leave it enabled on another node.
Many thanks!
Regards,
Lex

Lex,
As far as I know we dont need to do anythign manually. It should take care automatically once you tuned all the necessary tuning parameters.

Empty file in sender comm channel

i have issue with the empty files coming from the sender which are getting processed and getting saved in given file location.
Now the problem is,these files donot contain data and rather just gets outputted with header and trailer with some dummy data usually spaces,some zeros,-- like this...,this makes the file size of some 444 bytes or 834 bytes but as it is not having any data,we need to goto SXMB_MONI everyday,check for files,if its empty,needs to cancel them manually because it appears in red flag.
To avoid this,i was thinking of setting the empty file option in processing of communication channel to SKIp messages or delete messages.
Am i right in this approach?
From other thread:
"Currently when a process fails in PI due to an empty file the process needs to be manually set to u201Ccancelledu201D,where to locate in PI,what could be the problem and how it is to be solved.i have asked a similar question and hope that this error will help."
please reply and show me right way of resolving this.
thanks!
cheers!

Hi,
As per ur req, its nt possible in this way.
The empty file handling means the whole file is empty, the size is 0k.
So in ur req, empty file means Header and Trailer present, but no data Records.
we can achive this in following ways also,
1.write an adapter module, to check if at all there is atleast there is 1 Data record, if not throw exception there itself.
2.In the mapping check if at all there is any Data Record. If no Data Records raise exception and also the Alerts.

SAP PI 7.31 / Sender SOAP Channel Issue with XML tag Main/@versionMajor has incorrect value 000; expected value is 003

Hi PI Experts,
We are on SAP PI 7.31 SP 10.
We are in the process of integrating ARIBA P2P solution using SOAP Adapter as sender to connect Ariba with our PI system.
We have configured all required components in ESR and ID(Most of them are content provided by Ariba).When we try to post a message into PI using SOAP UI we are ending with below error.

http://<host name> : <port name> /XISOAPAdapter/MessageServlet?channel= <party name> : <service name> : <channel name>
For the above issue we had configured SOAP Sender channel as above,and the URL we are using to hit PI is as above screenshot.
We have followed the note on this topic with out any luck.
1378872
We are not sure where is problem.As the issue is not reaching to PI not able to see the messages in SXMB_MONI.
and in the SXMB_ADM PI has been configured as Integration Server.
I had even tried to change the message protocol as XI3.0 in SOAP sender channel and noluck.
I have tried to ximessage=true query also in URL and noticed that not working.This is clear that the message we are trying to send from Ariba is not compatible with XI3.0 protocol,Ariba is not having any option to change at their end as it is a cloud application and many customers have been using same with out any issues.
We have tried maintain the Java System properties in NWA as XPI.Adapter.Version.Major = 3 but no luck.
Can some one provide us the solution to get rid of this issue?

Sender file channel issue

Hello All,
Here I have a problem with sender file communication channel. THe channel is not able to pick a file as the file format is not correct andf throwing exception in the channel which is expected. But Its not allowing to go and pick the other files with correct format till I remove the bad file from the Source dir location.
How to get out of this issue Pls help me
Regards,

Hi,
Maybe you can delete or archive the erroneus file and then all the other files are processed?
Set checkbox Archive Faulty Source Files and give directory where the erroneus files are moved.
Also under module tab add new row int the Processing Sequence table like this:
AF_Modules/MessageTransformBean ............. 1
And in under Module Configuration:
Module Key ........ Parameter Name ...........................Parameter value
1 ......................... Transform.PermanentErrors .........true
If this won't help, please check the No[Note 1265534 - Archive faulty files does not work with add time stamp mode|https://service.sap.com/sap/support/notes/1265534]. Basically this means that archiving does not work if you have set the 'Add timestamp' option so check that too.

Please remember that empty files are handled with their own settings.

'No SOAP envelope' in Sender Comm.Channel

Check if XMLAnonymizer bean could be used on your sender adapter side and replace the SOAP namespaces with the ones defined in your SWCV.

JDBC Receiver Comm Channel Issue

Hi Team,
We have around 77 interfaces inserting/updating information into a database.
Q1) Should we creating 77 different receiver JDBC communication channels for the same receiver?
Q2) Or would a single JDBC communication channel suffice?
Currently, we have only created a single communication channel and we are encounter 'JDBC Message processing failed, due to Channel has reached maximum concurrency ' error.
The Maximum Concurrency is set to '1' for now.
Q3)How do we manipulate the 'Maximum Concurrency' value?
Please advice.
Thank you,
Rakesh.

it can be handled by a single on also

creating multiple channels allows the flexibility of manual start or stopping particular interface flows in some business scenarios. if it is a single CC then there is no flexibility. so it depends.

try increasing the value from 1 to 99 or the maximum permissible value

Sync/Async - JMS receiver comm. channel not processing

I have a Sync/Async scenario (without bpm) in PI 7.11:
RFC -> PI -> JMS
whereby the JMS receiver comm. channel does not fully process the message.
More specifically, the RFC sender comm. channel gets a message in and passes the message to the JMS channel, but that JMS channel within the RWB comm. channel log only shows the entry:
- Message processing started
The odd twist to this is that when we bring the PI server down, then back up again, (or wait a period of time, still trying to determine this period) the FIRST message attempt does successfully get processed, i.e. the first message on that JMS receiver comm. channel RWB log shows as:
- Channel successfully processed the message: 08499236-387c-11e0-b002-000025bab2c2
- Stored the correlation ID 08499236-387c-11e0-b002-000025bab2c2 of the request JMS message: ID:c3e2d840d4d8d4f24040404040404040c754dc12d8b54ec6 correponding to the XI message: 08499236-387c-11e0-b002-000025bab2c2
- Message processing started
(but then because of an issue on the target system, no response comes back, so then we'll additionally get the log entry:
- Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: no message received
Any suggestions appreciated on what I can check here to try and figure this out. Possibly because the first message eventually errors out, it is stopping the other subsequent msgs from getting processed...
When I check the audit logs of a 'success' msg vs. a not-successful msg, the success msg has an entry (and subsequent entries) of:
14.02.2011 12:50:19 Information Transform: transforming the payload ...
14.02.2011 12:50:19 Information Transform: successfully transformed
14.02.2011 12:50:19 Information ROB: entering RequestOnewayBean
14.02.2011 12:50:19 Information ROB: forwarding the request message
14.02.2011 12:50:19 Information ROB: leaving RequestOnewayBean
14.02.2011 12:50:19 Information JMS Message was forwarded to the JMS provider succesfully."
14.02.2011 12:50:19 Information XMB Message as Binary was forwarded to the SAP XI JMS service succesfully.
14.02.2011 12:50:19 Information WRB: entering WaitResponseBean
14.02.2011 12:50:19 Information WRB: retrieving the message for 08499236-387c-11e0-b002-000025bab2c2 ...
wheras the non-success msg shows only:
14.02.2011 12:55:30 Information Transform: transforming the payload ...
14.02.2011 12:55:30 Information Transform: successfully transformed
14.02.2011 12:55:30 Information ROB: entering RequestOnewayBean
14.02.2011 12:55:30 Information ROB: forwarding the request message
14.02.2011 12:55:30 Information ROB: leaving RequestOnewayBean
So, we can see that the message is not "forwarded to the JMS provider..." in the non-success case.
And also the sxi_monitor shows these messages with a status of "Log version".

Hi Siddhesh - yes that was a while back and am trying to remember the resolution. I have implemented sync/async bridges (as well as async/sync bridges) successfully, so I don't mind checking your settings, particularly I am interested in the settings within the Module tab of the JMS receiver. I can then compare to mine if you'd like. Also if you can let me know what underlying queuing system in that target system (e.g. MQSeries?) that would be great.

Keith

Sender - JDBC - Connection issue

Hi All,
I see a very strange issue on the JDBC Sender Comm Channel. On the Comm Channel Monitoring, I see it in GREEN. But it is not actually polling the DB table.
Restarted the channel and that did not work.
For now I have created a copy of the comm channel and the copy is working fine for couple days and again the same problem.
I created another copy and second copy is working fine till now.
Not sure what happened.
I think there are some open connections to the DB still hanging in there. I am wondering if there is any way of deleting or closing the open connections.
Thanks in advance.

Hi Naveen,
In your jdbc sender communication cahnnel go to advanced Mode tab --> there is a check box for Disconnect from Database After Processing Each Message. Select this option and give a try. This will make database connection released and reestablished before every poll interval.
Please see this help:

Content conversion at JMS sender communication channel

Hi friends,
I have to convert fixed length flat structure to xml message.Therefor i have to do content conversion at the JMS sender comm channel.Can someone please explainthe procedure?
data in the queue would be like as follows.
9999000000124646q12233appej500rc11147822zord

Hi Manikandan,
The structure conversion can handle files containing rows with different structures. In
each row there is a key field to identify the structure. The rows with identical key fields of
course have identical structures.
Let us assume that we have a sample file with four rows. Each row has a two-byte key
field; the first row has a second field with ten bytes; the structure of the second and third
rows is the same and comprises two additional fields with three bytes each; the last row
has a second field with five bytes:
AA1234567890
BBABCABC
BBXYZXYZ
CC12345
The configuration for the conversion could look like this:
Module Configuration
Module Key Parameter Name Parameter Value
Plain2XML Transform.Class com.sap.aii.messaging.adapter.Conversion
Plain2XML Transform.ContentType text/xml;charset=utf-8
Plain2XML xml.conversionType StructPlain2XML
Plain2XML xml.processFieldNames fromConfiguration
Plain2XML xml.documentName MyDocument
Plain2XML xml.documentNamespace http://xi.com/test
Plain2XML xml.recordsetName MyRecordset
Plain2XML xml.recordsetStructure NameA,1,NameB,*,NameC,1
Plain2XML xml.keyFieldName MyKey
Plain2XML xml.keyFieldType CaseSensitiveString
Plain2XML xml.NameA.fieldNames MyKey,field-nameA
Plain2XML xml.NameA.fieldFixedLengths 2,10
Plain2XML xml.NameA.keyFieldValue AA
Plain2XML xml.NameB.fieldNames MyKey,field-nameB1,field-nameB2
Plain2XML xml.NameB.fieldFixedLengths 2,3,3
Plain2XML xml.NameB.keyFieldValue BB
Plain2XML xml.NameC.fieldNames MyKey,field-nameC
Plain2XML xml.NameC.fieldFixedLengths 2,5
Plain2XML xml.NameC.keyFieldValue CC
In xml.recordsetStructure, you add a name for each different structure followed by the
number of occurrences or an asterisk for unbounded occurrences. For each structure
name, you configure the structure separately in a separate namespace such as
xml.NameA.fieldNames and so on.
If your source file is a CSV file, replace each xml.XXX.fieldFixedLengths with
xml.XXX.fieldSeparator.
the result of this conversion looks like this:
<ns:MyDocument xmlns:ns="http://xi.com/test">
<MyRecordset>
<NameA>
<MyKey>AA</MyKey>
<field-nameA>1234567890</field-nameA>
</NameA>
<NameB>
<MyKey>BB</MyKey>
<field-nameB1>ABC</field-nameB1>
<field-nameB2>ABC</field-nameB2>
</NameB>
<NameB>
<MyKey>BB</MyKey>
<field-nameB1>XYZ</field-nameB1>
<field-nameB2>XYZ</field-nameB2>
</NameB>
<NameC>
<MyKey>CC</MyKey>
<field-nameC>12345</field-nameC>
</NameC>
</MyRecordset>
</ns:MyDocument>

Vinod.
